Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Not really; trade changes things a bit, but not that much. It's that the cost of wind and solar has come down. A lot. So people are installing a lot.

well, according to ur article, Europe is indeed a serious emissions exporter! which confirms my opinion. Who makes windmills and solar panels ? Most of the time it is China, and thats how u import emissions: by selling affordable panels. Europe making their own panels would spare the chinese more pollution, thats it.

China really dominates solar, but a lot of wind turbines are made in the US and EU

all the better: but they also have to work on reducing their emission exports too and stop being hypocrite about how much polluting china is (if thoses stats stand true ofc)
